Pilot-scale study on the suspension of drill cuttings: Effect of fiber and fluid characteristics
( Elsevier , 2022 , Article)Drilling operation smoothness is essential to minimize drilling non-productive time (NPT). Inadequate cuttings transport can result in cuttings bed build-up in the wellbore low side, jeopardizing the whole drilling operation. ... -
Pinctada radiata (pearl oyster): A bioindicator for metal pollution monitoring in the Qatari waters (Arabian Gulf)
( Springer Nature , 1998 , Article)Bivalves are extensively used in monitoring programmes in the marine environment due to their ability to concentrate pollutants to several orders of magnitude above ambient levels in sea water. Commonly, the levels of ... -
The PiP model and progress in ground vibration from railways
( Australian Acoustical Society , 2017 , Conference Paper)Vibration in the ground causes problems. At large amplitude vibration causes damage, the most obvious example being earthquake damage. But the ground motion in a damaging earthquake is typically low-frequency (below 1Hz) ... -
